Oligosaccharide

An oligosaccharide (from the Greek oligos, a few, and sacchar, sugar) is a saccharide polymer containing a small number (typically two to ten) of component sugars, also known as simple sugars (monosaccharides). Oligosaccharides can have many functions; for example, they are commonly found on the plasma membrane of animal cells where they can play a role in cell–cell recognition.

In general, they are found either O- or 'f-linked to compatible amino acid side-chains in proteins or to lipid moieties (see glycans).
